IOOS Glider - sp034-20220315T1836

This dataset is comprised of routine deployments of two underwater gliders off the coast of Central California, inside or near Monterey Bay. Missions typically last several weeks, and include process studies inside Monterey Bay, or transects to ~250 km offshore from Monterey Bay. The gliders are equipped with a CTD to measure temperature, salinity, and depth, as well as biogeochemical sensors for dissolved oxygen, chlorophyll fluorescence or optical backscatter, and pH.cdm_data_type = TrajectoryProfileVARIABLES:trajectory (Trajectory Name)wmo_idtime (Profile Time, seconds since 1970-01-01T00:00:00Z)latitude (Profile Latitude, degrees_north)longitude (Profile Longitude, degrees_east)profile_idtime_uv (Depth-averaged Time, seconds since 1970-01-01T00:00:00Z)lat_uv (Depth-averaged Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)u (Depth-averaged Eastward Sea Water Velocity, m s-1)v (Depth-averaged Northward Sea Water Velocity, m s-1)latitude_qc (latitude Variable Quality Flag)longitude_qc (longitude Variable Quality Flag)time_qc (time Variable Quality Flag)depth (m)depth_qc (depth Variable Quality Flag)pressure (Sea Water Pressure, decibars)pressure_qc (pressure Variable Quality Flag)conductivity (Sea Water Electrical Conductivity, S.m-1)conductivity_qc (conductivity Variable Quality Flag)density (Sea Water Density, kg.m-3)density_qc (density Variable Quality Flag)precise_lat (Precise Latitude, degrees_north)...

本数据集包含两台水下滑翔机（underwater gliders）在加利福尼亚中部海岸蒙特利湾（Monterey Bay）内部或附近的常规部署任务。单次任务通常持续数周，作业内容涵盖蒙特利湾内部的海洋过程研究，以及从蒙特利湾向外海延伸至约250公里的断面观测。该滑翔机搭载有CTD（Conductivity, Temperature, Depth）以测量温度、盐度与水深，同时配备了溶解氧、叶绿素荧光或光学后向散射、pH等生物地球化学传感器。
